This invention is concerned with processes for refinishing the surfaces of materials in imitation of the natural appearance of other dissimilar materials and has for one of its objects the provision of a novel process for the simulation of a marble appearance on the surfaces of materials other than marble.

More generally, an object is to provide a novel and effective process for the simulation of natural subjects, such as marble, onyx, stone, wood and the like on the surfaces of materials dissimilar to those to be simulated.

More specifically my invention has for its are summarized in the claims.

.contour or outline.

In the drawings, in Fig. 1, I show a crosssection of a piece of material, the surface of wlnch has been treated to resemble the surface of a marble slab after the manner of my process; and Fig. 2 ma diagrammatic graphic representation of the application of several coatings ofpignients to a surface to impart to the surface a marble appearance.

My invention contemplates the use of the photographic method ofobtaining a metallic etching through a carbon resist and thereafter the etched plate or roll, as the case may be, has applied thereto pigments of different colors to simulate the natural colors of the surface to be imitated. These colors are successively applied. to the etched plate or roll and partake therefrom, the pattern in natural This may be accomplished by the use of a transfer roll and the transfers applied to the surface being treated in a certain color order whereby the apmanner to produce, for example, a zinc etchng or electrotype prepared therefrom and having the characteristics of the well known half-tone plate or a photogravure plate or roll. I prefer to use the latter. If it is desired to use a photogravure plate or roll, one step in the photogravure process may be omitted, namely, the making of a positive film or plate from the photographic plate or film. This produces a photogravure roll or plate which is in reality the reverse of the usual photogravure roll or late. When the plate is thus properly et-che it'is then ready v I or use.

A subject or material, the surface effects of which have been found to be simulated by my process with exceptionally good results, is marble. The following detailed description of the process will therefore be confined to this material.

I first treat the surface which is to be marbleizedwith a ground color A simulating in shade as nearly as possible, the natural shades or tones to be found in the'grai'n or cleavage marks of the natural marble which is to be imitated. This is, of course, a,comparatively light color. I then apply to the plate or roll a pigment or ink resembling in turn as nearly as possible another color to be found in the original marble slab in the grain or cleavage marks thereof. This color must be darker than the ground. After using a doctor blade to remove the surplus pigment and thereby leaving pigment deposited only in the etched interstices thereof, I remove the pattern thus outlined by the plate with a transfer roll and apply this pattern designated by the reference character B in the drawings, over the first ground coat previously applied to material to be treated by rolling the transfer roll thereover.

I then apply, after the coating which has been applied in the form of a transfer and has had suflicient time to dry, to the roll or plate, a pigment of still darker color, namely that resembling in tone the general or dominating color tone of the marble slab to be simulated and after using the doctor blade to remove the surplus pigment, I transfer a second pattern in this different color from the plate to the surface being treated, but apply this second pattern designated as C, and

whichin outline is the same as the first pattern B previously applied, to the surface but out of registration with the contour of the first pattern B. The second application produces an unusual result, in that portions of the ground color and the second color will show through the last applied color at the in the tones of the respective transfers, each 20 of which may vary throughout its surface; and also there will be variations from the initial pigment color of the respective transfers for example at E and E in accordance with the degree of showing of the color of the ground coating A through the transfers. The graphic representation shown in Fig.

2 however, is considerably exaggerated in.

that only small areas of ground color will be unobscured in the actual reproductions. A

protective transparent coating F of varnish or lacquer may be applied to impart to the treated surface the glossy appearance of polished marble.

This process, as will be readily understood, can be used for the application of more than two colors which will show at places on the surface unblended, while at other places where the pattern contours completely superimpose the composite color will vary in tonal depth. This result can'be obtained, as

above suggested, by the use of a photogravure, half tone, electrotype or any other printing surface derived through the use of suitable processes of producing printing surfaces by photographic methods.
